Free convective flow in an inclined square cavity with a partially heated wall and a cooled top surface
Abstract
Free convective flow in a rectangular cavity which has one 'side' wall partially heated to a uniform temperature and the 'top' wall cooled over its entire surface to a uniform lower temperature has been considered. All remaining wall surfaces are adiabatic. The cavity is, in general, inclined at an angle to the vertical. The flow has been assumed to be laminar and two-dimensional. The resultant equations, subject to the assumed boundary conditions, have been solved using the finite-element method. Results have then been obtained for Rayleigh numbers between 3000 and 100,000 for a variety of heated wall portion sizes and positions for angles of inclination between 0 and 180 deg. These results have been used to study the effects of the governing parameters on the mean heat transfer rate and these effects have been related to changes in the induced flow pattern within the cavity.
